2 Green Building Cluster of Lower Austria We are a network gathering abt. 230 partners architects, companies active in the green building and building refurbishment sector research centres, colleges and universities, industry, green building materials suppliers (timber, bricks, insulation material, HVAC ) and green electricians, Regional administration related to buildings & energy project promoters and building & timber contractors, carpenter, joiner information and promotion organisations and other networks (wood, natural materials, renewable energy, photovoltaic...)

3 Topics & results Core topics: refurbishment of old buildings to low energy buildings construction of new, multi-story structures to passive house standards healthy ecological interiors, enhanced living comfort Sustainable energy technologies and energy efficiency in companies > 320 cooperation projects since 2001 (~ 800 partner companies involved) project costs of 9mio and public support of 3.3mio since , direct value added effect triggered by project activities of the GBC with 14.6mio (study economic research institute ECONOMICA 2012) Cluster-Team: 4 persons specialised in civil engineer, wood-economic, energy expert, construction and interior design, energy

5 Team Members of Green Building Cluster of Lower Austria Martin Huber Alois Geisslhofer Clustermanager Susanne Formanek Michaela Smertnig We are specialised in civil engineer, wood-economic, energy expert, construction and interior design, qualification Our projectmanagers initiate, assist and accompany project from the idea to the publication

6 Specific strengths of the Green Building Cluster A critical mass of companies in the building sector on regional level from master builders to industrial building materials & systems producers, timber constructors, energy engineering companies etc. (in a distance of less than 200 km) The cluster is backed by ecoplus, the business agency of Lower Austria and belongs to the public sector, which is a driver of innovation also in the building sector (will be shown at the example of our own office building, walk the talk ) The target groups and partners of the GBC: more than 90% of our > 220 partners in the cluster are SMEs Clear targets, monitoring and reporting by a Balanced Scorecard system (BSC).

7 Main challenges of the cluster management Transforming the very traditional and SME dominated construction sector by promoting cooperation, research and innovation in joint projects influencing the regional administration/politics to establish favourable framework conditions for green building. focusing on combat of climate change: not only the energy performance, the whole life cycle of products and systems aiming at cradle-to-cradle : triple zero: zero energy, zero emissions, zero waste. contributing to education, skills & lifelong learning: qualification of more the 400 professionals in the field of a comprehensive building refurbishment acc. to the national climate:active standard.

11 Sonnenplatz Großschönau - test before you buy First Passive House Village allowing customers to test the house of choice by living in it for several days. Initiative combines technology and tourism promotion in a less developed region Ongoing joint research project of 17 companies to enhance the quality of the indoor environment in residential structures through controlled indoor ventilation: - Visitors will keep a log of their perceptions and experiences in regard to living quality - These subjective impressions will be compared with a wide array of measurable technical data - combined data will form a solid fact base which can be used by architects, builders, mechanical engineers and other professionals to design and build user-friendly ventilation systems

12 Building integriated Photovoltaik for the prefab house industry nominated Clusterland Award 2008 Österreichischer Fertighausverband Austrian association of prefabricated houses 2351 Wr. Neudorf 3 cooperating partners PV for the prefab house! PV is trendy but yet not standarized enough to penetrate the prefab-house marked. Idea of the cooperation was to create standards for a better implementation. Goal of the project is to reach the PV implemetation directly at the prefab industry.

13 Ways towards zero energy food stores REWE Austria Dienstleistungs GmbH 2355 Wr. Neudorf 4 cooperating partners nominated Clusterland Award 2008 Sustainability in the supermarket! Goal of this cooperation is to simulate the technical and economic basis for a zero energy-food store" on a prototype m² food-store-branche. Zero energy means the energy supply by active and passive elements is sufficient to cover the whole energy demand of the market for heating cooling light and airsupply.

14 gugler! build & print triple zero cradle to cradle in a printing plant gugler GmbH 3390 Melk 5 cooperating partners It aims at the development of a new sustainable building concept which works as plus energy house and fulfills all cradle-to-cradle criteria: triple zero: zero emission, zero energy und zero waste. a concept for a 100% recyclable eco-effective building (cradle-to-cradle) 2,140 m² useable floor area existing 3,260 m² useable floor area to be built architect Ursula Schneider >

15 MaizeCobBoard WoodKPlus Kompetenzzentrum Holz GmbH 3430 Tulln 4 cooperating partners Maize Cob Board (MCB) Light weight material from agricultural by-products Maize cobs accrue as an agricultural by-product can be used for a core material of light weight panels with good material properties and insulation characteristics. The aim was to work out a concept for the production and optimisation of material properties.

16 LOPAS- pre-fabricated timber constructed passive house with straw insulation and loam rendering LOPAS AG 3843 Dobersberg 3 cooperating partners The LOPAS Passive House The LOPAS Module Construction is a method of erecting a long lasting, energy-saving house in an ecological construction. Unique is above all the combination of clay, straw and wood. The modules are manufactured as floorto-ceiling elements thus guaranteeing quick assembly at the building site.
